tone function random crashes

[PaulStoffregen]

This sketch will crash after several minutes running on Arduino Zero. Serial output stops, and the frequency on pin 5 becomes approx 258 kHz.

void setup() {
  Serial.begin(115200);
  while (!Serial && millis() < 1500) ;
  delay(10);
  Serial.println("Tone Issue Test");
  delay(20);
}

void loop() {
  int frequency = 1500 + random(800);
  tone(5, frequency);
  Serial.println(frequency);
  delayMicroseconds(random(10000));
}

@aethaniel Any ideas?

Hi @PaulStoffregen, not yet as I didn't implement this API. I will check the code with @agdl but not before next Wednesday, unfortunately.

I'm in no hurry. Just wanted to make sure you knew about the crashing.
